Gardai believe a young mum and daughter were murdered in a jealous rage after her killer learned she was looking for love online.

Lithuanian Jolanta Lubiene, 27, and her eight-year-old daughter Enrika were found stabbed to death at their home in Killorglin, Co Kerry, last Sunday.

Officers established the mum was using dating sites and social networking pages to seek out new relationships.

And it is believed her killer learned about this before flying into a rage.

Gardai now fear the violent thug, believed to be known to the victim, is poised to flee the country and they are in a race against time to catch them.

From the start of the probe detectives have stated Jolanta’s internet activity and phone records will prove crucial in catching her killer.

Gardai have trawled through her laptop and mobile records for clues.

The movements of a number of individuals who were known to the mum between 2pm and 5pm on Saturday are also being investigated.

A senior source said: “The answer to this double murder lies within the Eastern European community in Kerry.

“Traditionally people in these communities have a natural fear and paranoia of police. But gardai are hopeful that people will see into their own conscience and do the right thing.”

In a bid to break through to the community gardai even released a statement in Lithuanian appealing for help.

Officers believe the killer fled out the back door of the house and into fields as he escaped the scene. There are 14 acres of fields behind the home and Garda teams from Limerick and Kerry continue to hunt for the murder weapon.

Today marks a week since the killings and gardai are expected to carry out checkpoints this afternoon in a bid to jog memories. No one has yet been arrested over the horror.

But forensic tests from the scene and on the bodies have been completed and cops believe the results will provide the evidence they need to nail the brute.

Jolanta tried to fight off the killer so skin and blood samples might be found under her fingernails and there were also bloody footprints at the scene which could yield vital clues.

The bodies of the victims were released this week and Jolanta’s husband Marius Lubys and sister Kristina Kuleviciene are desperately trying to raise the cash to fly them home for burial.
